python provides a great way of dynamically creating fuctions calls and
class names from string
a function/class name can be stored as string and called/initilzed
e.g
def foo(a,b):
return a+b
def blah(c,d):
return c*d
list = ["foo", "blah"]
for func in list:
print func(2,4)
or similar items
what is the way if the names of functions are some modification e.g
def Newfoo(a,b):
return a+b
def Newblah(c,d):
return c*d
list = ["foo", "blah"]
for func in list:
print "New"+func(2,4)
or define a variable
"New"+list[0] = "First Funciton"
I think , print "New"+func(2,4) and "New"+list[0] = "First
Funciton"
will not work, either eval or exec should be used
is it correct way, is there a simple way, is this techniqe has a name?
thanks
